Be it known that l, Riiss'ii'ni. hierna, a

citizen of the United States, residing 'at' lVillianistown, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in a y Gas Humidifier, of which the following is a specification.

` The invention relates to means for supplying moisture to gas in the operation of internal combustion engines. ManyV advantages result from the addition of moisture to the vgaseous Vmixture of internal combusf tion engines, hence it is desirable to render the gas moist. VBy supplying moisture to the gaseous mixture. the power of the engine is increased by the expansion of the mixture7 the cylinder is cooled, carbon prevented vfrom depositing and a saving of fuel results.

The drawings illustrate a preferredA ein-V Corresponding and like parts are referred to in the following` description and indi-l cated in both views of the drawings by like reference characters.

'I he humidifier embodies a vaporizer l which is adapted to be connected with the carburetor, not shown, in any suitable way so as to supplymoisture thereto in the forni of vapor. As indicated the vaporizer consists of two members which haveV a right anguiar arrangement. An exhaust pipe 2 extends through a portion of the vaporizer to heat the saine and convert the water into vapor or steam. The exhaust pipe Qis adapted to make connectionwith the exhaust manifold of the engine so as to carry off the spent gases. A cup 3 is attached to the exhaust pipe-2st; as to form in effect a part thereof, and this cup is ladapted to receive the moisture which is vaporized or converted into steam by the heat resulting from the passage ofthe eexhaust or spent gases .Y GAS Y 'i spcimen-ion 'f reiten-s :raten h' ie e with the L v formed between the cup 3 and the upper wall of the vaporizer l. The screen 4 ini sures the delivery ofthe moisture to the cup and assists materially in v'aporizing the water. v

A valvecasing 5 isfconnected with the vvaporizei' and asshown consists of a T-tting. Other fittings 6 and 7 are coupledl to Ythe branches-kof the lf-fitting 5. A supply f pipe 8 is coupled to the fitting 6 and is j adapted to be connected to the water jacket of the engine or to the upper portion of the radiator' or to any souiceof' water supply. A pipe- 9 is connected to the fitting `7 and is adapted to be connected to the intake inanif'oldy so that the suction stroke of 'the piston 'creates a suction therein whichis uti lized as means for automaticallycontrolling the valve whereby moisture is supplied'to the vaporizer.

A valve 10is mounted in the'fittingf? is adapted to close the opposing ends ofthe L.

supply and suction pipes. One uend of the valve l0 is made tapering as Vindicated vat 11 and shutsl ofi the supply by closing the endv of: the fitting 6 extending into the fitting 5. c rlhe opposite end of the valve 510 is provided with a disk 12 which closes the end of the ysuction pipe -9' adjacent and coupledto the fitting 7. An expansible helical spring 13 Y normally exerts a pressure on the valve 10 tok hold its end' 11 seatedr against the inner end of' the fitting 6 thereby normally shutting off the supply of moisture. The fittings 5 6 and 7 constitute ineifect the valve casing and the parts v10, ll'and l2 constitute an alternating valve,y because when the valve ll is seated, the' disc 12 is uns'eated and vice .y

versa.

in practice the supply pipe is adapted y to be coupled4 to a source ofsupply of inoisture and the'pipe 9 adapted to be connected to a part whereby a suction isereated therein. The supply of moisture is noi'-` mally cut oif' by the valve 11 in the manner stated. lWhen Vthe engine is running and suction is created in the pipe 9,- the valvey 12 is drawn to its seat thereby unseating the drawn into the vaporizer by the suction y through the carbuietorin a manner well understood. The moisture entering the vaporizer is received inthe; cup 3 and'S convertvalve 11 and admitting ofV moisture being i y Letters Patent, is

ed into Steam or vapor by the heat of the exhaust or spent gases passing 'through the pipe 2.

Having thus fully described my invention what I claim as new and desire to secure by A device of the character described com prising a chamber, an exhaust pipe vextending into said chamber, a cup resting'upon saidv exhaust pipe Within said chamber, a

Y porous suspension cylinder for said cup, a

Water supply pipe, a union connecting said porous suspension cylinder with said VWater supply pipe, a valve mechanism adapted to control the entrance of Water from said supply pipeY to said cup, and suction means acting directly upon the valve for controlling the operation thereof.
